Now, let’s explore how to enable SSH on your Fedora system.
Step-by-Step Guide to Enable SSH on Fedora
Enabling SSH on Fedora is a straightforward process. Just follow the steps below:
Step 1: Open Terminal
To initiate the process, open the Terminal application on your Fedora system. You can do this by pressing the Ctrl + Alt + T shortcut or by searching for Terminal in the Applications menu.
Step 2: Install OpenSSH Server
Next, you need to ensure that the OpenSSH server is installed on your Fedora system. Execute the following command in the Terminal:
sudo dnf install openssh-serverThis command will install the OpenSSH server package, allowing your system to communicate securely over SSH.
Step 3: Start and Enable SSH Service
Once the OpenSSH server is installed, start the SSH service using the following command:
sudo systemctl start sshdAdditionally, to ensure that SSH starts automatically on system boot, enable the service with the following command:
sudo systemctl enable sshdWith these steps completed, SSH is now enabled on your Fedora system! You are ready to establish secure remote connections and experience the power of SSH.
The Advantages and Disadvantages of Enabling SSH on Fedora
